Which diagram should you actually use as a BA? It's a question I was asked recently... and it got me thinking. There are so many visual tools available... process maps, context diagrams, journey maps, ERDs, prototypes… the list goes on. The trick is: → You don’t need to be a master of every single one. → You just need to know what each is for, and when it makes sense to use it. ... and MOST importantly - the goal isn’t textbook perfection → it’s to create a picture of the work in a way stakeholders can understand. It’s about storytelling and collaboration, not perfect notation... Here’s how I think about it 👇 1️⃣ Core BA tools Process models, journey maps, context diagrams, use case diagrams. These are our bread and butter. 2️⃣ Shared tools ERDs, DFDs, state diagrams. BAs often co-create these with data or solution team members. 3️⃣ Specialist tools Sequence diagrams, wireframes. Not always BA-owned, but we’re often involved. That’s why I pulled this cheat sheet together (see carousel). Save it for later 🔖 Which one do you lean on the most in your projects?

📌 Don’t stress about textbook perfection. You’ll always find “experts” who say “that’s not how it’s done.” The most important diagram is the one your stakeholders can understand, because it tells a story and paints a clear picture … whether it’s of current state or the future state you’re working towards.
Matthew Thomas Holliday I would move ERDs into the "Core" - they certainly are for me - and why wouldn't you class DFDs as a sort of "Process Model" ?
This is an awesome carousel! 🌟🌟 The diagrams I used most lately were report mockups (although they were tabular spreadsheets) and what I've heard called an Ecosystem Map that shows how systems are interfacing for my relevant solution.
wow, Matthew Thomas Holliday. This cheat sheet is gold. It makes it so easy to know when to use what.
Good Insights Clear and concise!
True gem for any BA thanks for sharing buddy
Thank you for sharing such valuable insights. This will greatly support understanding the different types of diagrams that Business Analysts should be familiar with—knowing not only how to use them but also when to apply them to best serve their purpose.
These tools and the way you explained them is awesome.
